iguana burn

Question
I was holding my baby iguana and I saw a small white spot surrounded with alil tint of grey. Behind his arms is it a burn and if it is what should I do ? They don't look serious at all .    ...

Answer
First, there should be no way for your iguana to burn itself--if there is, correct that immediately.  Second, I'm not sure how it would get a burn in that spot.
Third, I couldn't even remotely begin to guess without a photograph.  If you think your pet is injured, you should take it to a veterinarian.
